As a Physician who is deeply engrained in the world of Sports Medicine, the science behind what John is doing at Gateway CrossFit is spot on. My training sessions were specifically tailored to the needs of my body; in my case, it was working on my posture and correcting my implicit desire to constantly round my shoulders and hunch over. In addition, the WOD (work-out of the day) was a cardio explosion! Rarely are trainers able to incorporate both lifting and cardiovascular fitness! … [Read more...] about Dr. Tate Greditzer

By the first of the year in 2012, I was overweight. And, I was miserable. My diet was terrible, and my exercise routine was sporadic and boring. I was a member of a fitness club that I hated, and I could barely muster up the motivation to workout. I needed something different. I tried Crossfit after hearing other’s testimonials. The first session was free, so I figured “what the heck?” I remember working intensely that day. Mark (one of Gateway’s personal trainers) pushed me harder than I … [Read more...] about Lisa P.

It was with no small amount of trepidation that I decided to join Gateway Crossfit. At the ripe old age of 45, I had never belonged to a gym, never lifted weights, and sure as heck never had a personal trainer. I was concerned that I would be overwhelmed and ultimately fail. I could not have been more wrong. John was able to tailor a workout program that not only fit my needs but recognized that I was starting on the ground floor. I have progressively gotten stronger and increased my … [Read more...] about Pete Fister

Mark’s has a true passion for his job and that translates over into his in-depth approach of reaching his client's individual personal training goals.

I first got introduced to CrossFit back in 2008 with a trainer I was working out with at the time. After just a brief few months of training he ended up moving, but introduced me to a few guys at the gym who were familiar with CrossFit that could assist me if I needed help. One of those people was John Seiler. Before long, I was doing CrossFit with John 3 or 4 times a week. Previously, I had worked with a number of different trainers and did various workouts but none got me the results like … [Read more...] about Lindsay Melvin

I started at Gateway CrossFit in May of 2011 weighing 232 pounds, the heaviest I had been in ten years. Going into my training I was a bit intimidated after reading about the workouts, watching others in the gym, and knowing my current fitness situation. Mark and John both not only reassured me that I would be able to do the workouts;they spent time explaining and showing me what we were going to do and the correct way to lift and/or move during an exercise. The weight loss was a big deal to … [Read more...] about BJ Baker; 198lbs. (and counting)
